PART 1 BLADE SELECTION CHARTS
NOTE - CHART GUIDE ONLY
This chart is issued as a guide only. Many other factors would attribute to the cutting
performance of both the saw blade & the cutting saw machine. BROBO GROUP Pty.
Ltd. will not accept any responsibility for the blade selection and/or machine breakag-
es or unsatisfactory cutting performance of both the blade and/or the machine as a
direct result of the selection.

PART 2 INSTALLATION
Upon receiving the Brobo Group S315G/S350G/S400G Series Metal Cutting Saw, the ma-
chine should be standing upright & positioned centrally on top of a wooden pallet.
While the machine is situated on the pallet, position the forklift arms under the pallet between
the runners, keeping in mind that the machine is head heavy.
Move the entire unit to an accessible area as close as possible to the final location.
Carefully remove the wooden frame surrounding the saw unit. Once completed, proceed by
elevating the machine away from the pallet base using a sling harness wrapped around the
cutting head of the saw. Ensure that the floor is as level as possible before finally positioning
the machine to the desired location.
Along with the saw unit, check that the following accessories, packed “loose”, are included
as follows:
STANDARD ACCESSORIES
• 1 x Saw Blade
• 1 x Operating Handle
• 1 x Service Kit (Allan Key 10mm & 14mm)
• 1 x Operating Manual (Softcopy - Download from brobo.com.au)

WARNING - HEAD HEAVY MACHINE
The metal sawing machines are heaviest where the saw heads are fitted & as such,
care must be taken while relocating or moving the machines.

8 Fowler Road Dandenong South Vic 3175 brobo.com.au 6 [phone] [email protected] 7
PART 2 INSTALLATION
For the machine to function correctly, the room in which the saw unit is to be installed must
be in the vicinity of, & satisfy the following conditions:
REQUIREMENTS
• 415/240V Power Supply
• Ambient Temperature: From -10°C to +50°C.
• Relative Humidity: Not more than 90%.
• Lighting: More than 500 LUX.
ANCHORING THE SAW
The base of the fabricated stand in which the
saw head rests on, is anchored to the floor by
4 x M12 bolts provided. For added stability, it is
strongly recommended that the machine stand
is fastened to the floor by using loxins (not pro-
vided). When positioning & fastening the unit,
please refer to the hole locations shown
OPTIONAL ACCESSORIES
• 9311270 Standard Adjustable Length Stop (600mm)
• 9501560 Micro Flip Over Stop Complete Including Arm
• 9501460 3 Metre Broborule Length Stop Kit
• 9501480 6 Metre Broborule Length Stop Kit
• 9311060 Manual Vice Assembly
• 9301950 Manual Dual Arm Vice
• 9501090 Gearbox Oil
WARNING - OPERATING VOLTAGE VARIATION
Each saw model has an inbuilt safety system to protect it against voltage variations.
However, for the machine to perform efficiently, ensure that the saw unit operates
within 10% limits of the recommended voltage of the motor.

PART 2 CONNECT TO POWER SOURCE
POWER SUPPLY
The 415/240V power supply requirements for this machine are of a high level & unautho-
rized interference and/or inadequate maintenance could result in a situation that could put
the operator at risk. A qualified electrical engineer should always be assigned to maintain &
repair the system.
International Protection Rating code (Ingress Protection): IP54
First Digit: Solid - Level 5: Protected from limited dust ingress.
Second Digit: Liquid – Level 4: Protected from water spray from any direction.
SINGLE & THREE PHASE
Single phase machines are provided with three pins, 15 amps rated plugs & leads for con-
nection to 240V, 50Hz power supply in Australia.
Active = BrownBrown VOLTAGE MAIN VOLTAGE
Neutral = Light BlueLight Blue 240V/1 PH 240V
Earth = GreenGreen/YellowYellow
Three phase machines should be fitted with a suitable, approved four pin plugs
Active = BrownBrown , White. Dark Blue VOLTAGE MAIN VOLTAGE
Earth = GreenGreen/YellowYellow 415V/3PH 415V/3PH
WARNING
Before connecting the machine to the power supply, check that the socket is not
connected in series with other machines. This condition is critical for the ideal op-
eration of the saw unit.

8 Fowler Road Dandenong South Vic 3175 brobo.com.au 8 [phone] [email protected] 9
PART 2 CONNECT TO POWER SOURCE
TO CONNECT THE MACHINE TO THE POWER SUPPLY, PROCEED AS FOLLOWS:
1. Insert the power plug into the socket, while ensuring that the mains voltage is compatible
for which the saw unit is operating at.
2. Switch the saw on by rotating the control switch located on the saw head assembly as
shown below.
3. Check that the motor is operating in the correct direction, that is the blade is rotating-
downwards & into the direction of the vice clamps.
4. Ensure that all electrical leads & cables (including supply leads) are maintained in a good
condition
WARNING
Check the power supplied & motor specifications before plugging in the machine.
Check the terminal connection on dual voltage motor terminal box & connect it ac-
cordingly to the corresponding voltage supply.
If the dual motor is requested, the motor is always connected to the higher voltage,
unless otherwise specified prior to the order being placed.

PART 3 SAFETY & ACCIDENT PREVENTION
The Brobo Group S315/S350/S400 Series Metal Cutting Saw has been designed & man-
ufactured in accordance with Australian Standards. It is HIGHLY RECOMMENDED that the
instructions & warnings contained in this chapter be carefully followed for correct usage of
the machine.
OPERATION OF THE MACHINE
The Brobo Group S315/S350/S400 Series Metal Cutting Saw is specifically designed to
cut ferrous & non-ferrous metal cross sections with solid or thin-walled profiles. Other types
of material & machining are not compatible for use with the specifications of the saw. This
machine involves a high-speed blade rotation; therefore extreme caution is required when
operating the device.
The employer is responsible for instructing the personnel who, in turn, are obliged to inform
the operator of any accident risks, safety devices, noise emission & accident prevention reg-
ulations provided for by national & international laws governing the use of the machine. The
operator must be fully aware of the position & functions of all the machine’s controls.
All those concerned must strictly adhere to ALL instructions, warnings, & accident prevention
standards in this manual.
The following definitions are those provided for by the EEC DIRECTIVE ON MACHINERY No.
98/37/CE:
Danger Zone - any zone in and/or around a machine in which the presence of a person con-
stitutes a risk for the safety & health of that person.
Person Exposed - any person finding him or herself, either completely or partly in a danger
zone.
Operator - the person or persons are given the responsibility of installing, operating, adjust-
ing, maintaining, cleaning, repairing, & transporting the machine.
NOISE LEVEL
The noise level of an idling metal saw, fitted with a 180-tooth blade (supplied as standard
by Brobo Group) has been measured to be below 85 dBA. This complies with the Australian
Occupational Health & Safety (Noise) Regulations 1992.
Please note that peak impulse noise levels will be experienced due to variables including blade
characteristics, type, & condition. This will also vary accordingly depending on the size &
type of sample being cut. Under these circumstances, management should make available
to the operator(s) the appropriate hearing protection equipment as prescribed under the
above-stated act.
WARNING – UNAUTHORISED MODIFICATIONS/REPLACEMENTS/USE
The manufacturer declines any responsibility whatsoever, either civil of criminal,
in the case of unauthorised interference or replacement of one or more parts or
assemblies on the machine, or if accessories, tools & consumable materials used
are different from those recommended by the manufacturer, or if the machine is
inserted in a plant system & its proper function is altered.
